The present invention relates to jetties or stream barriers of the type used in a. flowing stream or current for forming a silt bar or the like.

Among the objects of the invention are to provide a novel jetty and jetty sections which may be located in a iiowing stream or current and capable of` efficiently collecting silt for forming bars and the like; to

rovide a jetty with an inclined surface or ace upon which the silt may be deposited or held in place; to provide a jetty with longitudinal elements, spaced and extend ing so as to aid in collecting silt, and preferably, to support a silt collector, such as wire mesh material or the like; to provide a jetty with open mesh material, such as fwire fabric, for the depositinv thereon of the silt; to provide a. support for the same, preferably comprising a longitudinal bar, to which may be fastened or secured one or `more transverse bars, preferably intermediate their ends, and means, such as strut or supporting bars, preferably fastened at one end thereof tothe first mentioned bars, for

holdingfthe latter in an inclined or oblique position whereby the fabric may be supported 'thereon 'in position forthe silt `collect-ion; to provide on such supports longitudinal supporting elements, preferably, 1n the form of cables or wires extending the length of the jetty or barrier with the ends of the cables preferably connected at their ends to an end cross bar or transverse bar of the jetty at each end thereof, to the end of aiding in supporting the wire mesh; to`

connect the supporting sections in a line or row by connecting the adjacent en'ds of the longitudial bars together, and holding t-he sections in `place by suitable anchoring means, such as tie elements from piles in the bed of the stream or bank and dead men in the bank; to provide for a permeable barrier, if desired, at the rear of the jetty to aid in retarding the rate of'iiow of the stream and in the collecting of the silt upon the-barrier and jetty, the barrier preferably being a series of groups of trees or branches extending rearwardly from the jetty and secured thereto in suitable manner; and to rovide such other objects, advantages' and) capabilities as will later appear and are inherently possessed by the invention. v

Referring to the drawings showing an illustrative embodiment of the invention, Fig. 1 is a view in perspective of a stream or river in which t-he ljetties are located; F ig. 2 is a perspective view of a unit or section or segment constructed in accordance with the invention; Fig. `3 is a front view of the same, and, Fig. 4 is an end View of the same.

Referringmore in detail to the draw-ings, the invention isV shown in use in Fig. 1 Where sections are connected together longitudinally and the line of sections are held in place by suitable connecting or tie elemel'its land 2 respectively connected to dead men 3.buried in the `bank of the stream or piles 4 sunk in the bed of the stream. 4 The bank. end of each" barrier or jetty may also be connected by a suitable element 5 or 6 secured to dead men 7 `and 8 also buried in the bank. i

`At the rear of each jetty may be located a series of trees or branches 9 suitably connected `to the jetty or jetty sections byl tie i elements preferably connected `to the zontal section bars of the jet-ty.

Referring more particularly t0 Figs. i 2,

3 and 4, each section is shown as comprising a longitudinalvbar 10, preferably `of angle iron to which maybe secured, at a distance from the end of the bar 10, a pair of substantially parallel spaced transverse bars 11 and 12, also preferably of angle iron, and supporting or strut bars 13 and 14 which are preferably secured at an end thereof to the 'longitudinal and-transverse bars at the juncand transverse lbars form a` sort of double eros-s which is held in inclined position by the strut bars 13 and 14. The jetty is composed of these angle Abar constructions as sections or segments of the jetty, any num- .ber of'sections being arranged in a row or line to the desired length of the jetty to be placed in thel stream as shown in 'Fig'. 1 of the drawings. In order to connect the sections or units in alinement, the longitudinal bars are provided at the ends thereof with loq suitable apertures or openings 15 and 16 through which may be passed the connecting element 17, preferably wire or simi-larA connecting means. The weight of the sections is sufficient to hold them inplace on the bed of the stream and the rolling of the jetty is prevented by the tie elements l and 2 connected to the dead men 3 and the piles 4. The connecting elements 1 and 2are preferably connected, at the jetty ends, to the longitudinal bars 10 as clearly shown in Fig. 1 of the drawings. i j

For the purpose of aiding in collecting the silt upon the face of'the'jetty, the face being that of the longitudinal and-transverse bars, strip-s 'or sheets of Wire mesh or like fabric 18 may be placed to overlie such face. `This wire fabric is preferably in long sheets that may be laid upon the face of the sections for the total length of a jetty, the strips being out at the ends of the jetty. A nuinber of these strips may be placed upon the jetty side byside so as to completely cover the face thereof. In the specific'form shown three strips are shown but it is to be understoodany number of strips may be used depending upon the total width yorvheight of the face of the jetty.

` lVhile these stripsmiay be sutliciently supported by the longitudinal and cross bars of the jetty section, yet, when it is desired to support them more efficiently, the jetty may be provided with a *plurality of spaced longitudinalelementslQ, preferably of Wire or cable extending the full lengt-h of the jetty. These elements are connected at their ends to the end cross bars 20 and 20 of the end sections ofthe jetties as shown in Fig. 1 of the drawings.. The elements are then extended through suitable perforations or holes 22 and 23 provided in the cross bars 11V and 12 of the sections as clearly shown yin F 2, 3, and 4 of the drawings. The vsheets or strips of Wire mesh '18 may rest upon. these elements and are preferably secured to these elements by suitable securing means 24, preferably Wire or the like.

`In order to aid; in the collection ofthe silt upon the jetty and in rear of the same so as to build up a bank or vprevent the erosion of the bank at the side of the stream a barrier of a permeable nature maybe located at the rear of each jetty, this barrier being Apreferably formed from a series or bunches of trees or branches 9 as clearly shown in Fig. 1 of the drawings. These trees are placed substantially horizontally and'extending rearwardly from the jetty 4with the stems or trunks of the trees connected to the jetty sections in suitable manner, as by `cablesv or wires fastened Vto 'the longitudinal bars 10 of` the4 sections of each jetty. These trees are hunched together so tlgjatthey vyillextendfa given distance above the normal sla-151118.66 O19 `level of" the" stream,

They act to retard therate of iloW of the stream so the silt and suspended matter in the Water Will have a chance to be deposited upon the jetty as Well as upon the branches ofthe trees, and at the rear of' the same.

The. sections ofr the jetties are so positioned upon. the bed of the stream to preferably present the sheet of material 18 on the up-stream side of the jetty so lthat it may efficiently gather or collect the silt and zont'alvplane when positioned in the flowing.

stream, upstanding bars spaced longitudinally of the first mentioned bar, struts connected to the juncture of the horizontal and upstandingbars for maintaining the upstanding bars in erect position, said upstandingbars vand struts being adapted to have their lower ends lieuponf the bed of the stream and a net Work of Wires extending over the front face of the jetty and being coextensive Withthe height'of the upstandng bars and the length of the longitudinal 2. A jetty comprising a longitudinal bar adapted to vextend across the stream, spaced upstanding bars fastened intermediate their ends yto the longitudinal bar, struts vinclining rearwardly and .connected at their upper ends to juncturevvof the former bars, 'j the lower ends of the struts and upstanding bars being adapted to rest upon the bed of the stream, and a networkl of Wire coveringV the faceof and coextensive with and longitudinal' bars.

3. A jetty comprising a longitudinal metal angle iron, adapted lto .extend across the stream, spaced upstandng metal angle irons fastened intermediate their ends to the longitudinalbar, said upstanding members being maintained in erect position by means of the upstanding struts secured to the juncture of the upi standing and longitudinal members and the lovverends of said struts and upstanding members being'adapted to rest upon the4 bed ofthe stream, andV av wire mesh' screen fastenedto and covering the entire areaem' f braced bythe extremities of the upright and longitudinal membersy and. disposed upon the side' opposite' fromv Whichfthe strutsy project.

4. A jetty comprising a. longitudinal; metal nov angle iron adapted to extend across the stream, spaced metal angle irons fastened intermediate their. ends to the longitudinal iron and disposed transversely thereto, struts attached to the junction of the longitudinal and transverse irons and extending downwardly and outwardly to form supports for holding the transverse members in upwardly inclined position, a plurality of Wires connecting the transverse members and Aextending in spaced relation parallel to the longitudinal member, and Wire screening covering the entire area of the wires.

5. In a jetty the combination of a longitudinal angle iron having a plurality of uprights connected thereto inter-'mediate their ends and spaced longitudinally thereof, a strut fastened tothe juncture of the longitudinal and upright members Jfor holding the latter in inclined position, said uprights having a plurality of vertically spaced holes, and Wires passinfr through the holes and extending a parallel spaced relation longitudinally of the longitudinal Aangle iron, and Wire screening fastened to the Wires and to the angle irons.

6. In a jetty the combination of a. jetty composed of angle irons arranged to restI upon the bed of the stream with some irons o the jetty standing erect, silt detaining members carried by `the jetty, cables connected to the jetty for anchoring the jetty in position in the stream, and a plurality of cables connected to the jetty and extending rearwardly thereof and trees anchored by means of said rearwardly extending cables to the jetty, said trees extending rearwardly of the jetty.y
